No, this is just one more reason to move back to 1.37x level firmware.
Besides, what's the problem? The nice thing about owning an Orion I is the
ability to run 1.x or 2.x firmware. At this point, I think 1.x will work
better for me than 2.x does. I may change my mind after a few weeks on the
older level, but, no big deal, I'll just load the later level again!

Wait a minute. Change radio firmware because you're not happy with
headphone levels?
As a frequent audiophool who has owned many sets of headphones .. It isn't
the audio system's fault that one headset requires a high audio setting and
another one doesn't require a setting much higher that a tweak. Headsets
are DIFFERENT. It has much less to do with the favored excuse of an
impedance mismatch or the Orion's output Z or the presence of the headphone
mod or whatever, than it has to do with the voltage levels required to
produce a given SPL from a specific set of headphones. Unless radio
manufacturers include a separate headphone volume control it's just a fact
of life. And it certainly has little to do with the Orion's firmware
version.
(A quiet prayer ... Lord, please don't let this become the next the next
rant for something else to do with the MULTI control).
The way around those differences is a headphone amp. For radio use, you
don't need to spend a grand. You can spend a few bucks. I certainly
wouldn't replace many-K-$ worth of high end audio gear with some Ratshack
stuff because my latest headphone purchase required a different output level
set than the speakers. Would someone replace their multi-K-$ radio because
they don't like the way it works with their $100 crummy headphones?
And this certainly isn't an "Orion problem" as some have suggested. We
don't live in a perfect world where every headset has precisely the
efficiency as some ASA or IEEE standard, thank goodness. And impdedance has
nothing to do with 'efficiency'. Anyone old enough to remember the AR
Acoustic Suspension audiophool phase would know that first hand. Some of
the very best headphones require huge amounts of drive (which is not to
imply the Heil headset, if it requires a lot of drive, is by any stretch of
the wildest imagination, a good headphone).
We need to get feet and perspective back on the ground here :)
